Be it known than, HERMANN J. L. BLANKE,

ers skilled in the art tov which it appertains tomake and use the same.

My invention relates to a novel construction in a device for receiving written notices, y65e., during the absence of a doctor or other business man, the object being to provide a device of this character which provides the paper and surface for Writing and devices for hiding such writing from the eyes of all -except the person for whom it is intended; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a perspective View of my device. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a detail sectional view of same on the line 3 3 of Fig.

' 2. Fig. 4 is a detail sectional view on the line 44 of Fig. 3. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 3. Fig. 6 is a sectional view similar to Fig. 5, showing the parts in different positions. in elevation, partly broken away, of the rear plate of the device. Fig. 8 is a detail sectional view on the line 8 8 of Fig. 2. Fig. 9 is a detail sectional view showing a locking device omitted in Fig. 2. Fig. is a sectional view on the line 10 10 of Fig. 9. Fig.

' 11 is an end elevation of the top plate of the device.

Referring now to said drawings, A indicates a hollow metal plate, to which a casing B is pivoted by means of hooks 1, entering slots in the lower end of said plate A. Said plate A is also provided with a lock 2, operated by a key 3 and adapted to engage a hook 4 on the upper end of said casing B to lock the same against said plate A. A button 5, having a shank 6 passing through said plate A within said casing B, carries a disk 7, revoluble within said hollow portion. of said plate' A, said disk 7 having a dial S, perceptible at Fig. 7 is a view one point through an opening 9 in said plate A. A rod 10 is pivoted upon said shank 6 of said button 5, and at its upper end vcarries a segmental plate 11, containing words, such as Return at and At home, said plate being partially perceptible through the opening 12 in said plate A, and at its other end said rod 10 is provided with a small arm 13, passing through the segmental slot 14 in said plate A, by means of which said rod is turned on its pivot. Said casing B is provided with two parallel sides 15, provided with lugs 16, through which screws are adapted to pass to secure the compound curved plate 17 thereto. Inclined recesses 18 between ribs 19 on said sides serve tol receive and hold the reel 20, upon which a roll 21 of paper is mounted. Said paper is passed over a roller 2 in the upper front portion of the machine, thence underneath the slotted top plate 23, over the roller 24, and downwardly between the rollers 25 and 26. A plate 27 is mounted below the plate 23 and is provided with down- Wardly-extending lugs 2S on each side, which are recessed, so as to rest pivotally upon a tubehereinafterdescribed. Thepaperpasses over said plate 27, which provides a smooth firm upper surface to enable the paper to be written upon. The shaft'of the roller 26 passes through one of said sides 15 and carries a knob or button 29, by means of which it can be turned. A ratchet-wheel is also mounted upon said shaft of said roller 26 and is adapted to prevent said roller from being turned except in the direction to draw said paper from its reel, a pawl 31 being pivoted upon a shaft 32 and held in engagement with said ratchetwheel by means of a spring 33 to prevent rotation in the opposite direction. Said shaft 32 is rigid, being reversely threaded at its ends and serving to hold the upper ends of said sides 15 rigidly in relative position. Upon the other end of said shaft 32 a bell-crank lever 34 is pivotally mounted and held frictionally against free rotation by means of the spring 35 bearing against the same. The arms 36 and 37 of said bell-crank lever 34 are of different lengths and are adapted to beV IOO the roller 26, while the arm 37 supports the plate 27. Upon applying pressure, such as the weight of the hand, upon the plate 27 the arms 37 and 36 will be depressed, as shown in Fig. 6, thus releasing the pin 38 and enabling it to turn freely. Such depression of the plate 27 brings the arm 37 into the path of the pin 38, which as it revolves raises said arm 37 out of its path, and thereby raises the plate 27 and at the same time brings the arm 36 again into its path. In this manner a given length of paper will be passed at every revolution of the roller 26 and undue waste be prevented. Said plate 23 is removably mounted upon said casing B by means of perforated lugs 39 on the sides of said plate, which are adapted to enter sockets 40 on said sides l5. The inner walls of said sockets are perforated in alinement with said perforations in said lugs 39 when the latter are in place, so as to enable pins 41 to pass through both said perforations. Said pins 4l are telescopically mounted in a tube 42, extending between said sockets 40, and are normally held at the outer limits of their movement by means of the springs 43. Said pins 41 are each provided with lugs 44, moving in slots or recesses 45 in the ends of said tube and adapted to enter recesses 46 in the inner faces of the inner walls of said sockets 40, and when said lugs 44 have entered said recesses 46 said pins move to the outer limits of their movements and enter the perforations in the lugs 39, thus engaging and rigidly holding said lugs and said plate 23 in position. By turning said tube 42 by means of an arm 47 thereon, so that said lugs 44 leave said recesses 46, said pins 4l will be Withdrawn from said perforations in the lugs 39, and will thus release said plate 23. The plate 27 pivotally rests upon the said tube 42, as hereinbefore mentioned. Said plate 23 isn provided on its forward end with an angular extension 48, provided with a slot 49, through which a name-plate 50, secured to the-rear face of said extension 48, can be seen.

My device is simple, eiiicient, durable, and cheap and, as will be obvious, is constructed witha View to prevent any tampering with any part thereof. After an absence the owner` of the device inserts his key and turns the casing B upon its pivot. He then tears off the free end of the paper, such tearing being aided by the serrated plate 5l, and reads` the, notes.
